Idume ngamandla ayo aphezulu okutyhala, uxinano oluphantsi, ukumelana nokugqwala okugqwesileyo kunye nokuhambelana okuthembekileyo kwezinto eziphilayo, i-titanium alloy sisixhobo esiphambili solwakhiwo esisetyenziswa kakhulu kwi-aerospace, izixhobo zonyango, ubunjineli beekhemikhali ezintle kunye nokuveliswa kwezixhobo eziphezulu. Ngokungafaniyo nezixhobo zesinyithi eziqhelekileyo, i-titanium alloy inovelwano kakhulu kutshintsho lobushushu ngexesha lokubumba. Isantya sokuphola, indawo yokupholisa kunye nendawo yokupholisa emva kokubumba zimisela ngokuthe ngqo ulwakhiwo lwangaphakathi lwengqolowa, imeko yoxinzelelo olushiyekileyo kunye neempawu zokugqibela zoomatshini zeendawo ezibumbayo. Ukukhetha i-alloy efanelekileyo indlela yokupholisa yokwenza i-titanium Kubalulekile ukuzinzisa umgangatho wemveliso, ukuthintela ukuguquka nokuqhekeka, kunye nokuqinisekisa ukusebenza kakuhle kwebhetshi.
Izinto zokuLungisa iTitanium ngemigangatho eyahlukeneyo, izakhiwo kunye neemeko zenkonzo zifuna iinkqubo zokupholisa ezahlukeneyo ngokupheleleyo. Ngokusekelwe kumava okwenyani okwenziwa kwe-industrial, eli nqaku lizisa iindlela ezintlanu ezisetyenziswa rhoqo zokupholisa i-titanium alloy forging, ligubungela imigaqo yazo yokusebenza, iingenelo ezisebenzayo, imida kunye neemeko ezifanelekileyo, ukuxhasa ukukhethwa kwenkqubo ngokuchanekileyo kunye nemveliso esemgangathweni.
1Ukupholisa Umoya Wendalo
Ukupholisa umoya wendalo yeyona nkqubo ilula nesetyenziswa kakhulu yokupholisa kwiindawo zokusebenzela zokufakela i-titanium. Emva kokufakela kokugqibela, izinto zokusebenza ze-titanium zifakwa ngqo kwindawo enobushushu obuqhelekileyo kwaye ziphole ngokwendalo ngokusebenzisa i-convection yomoya kunye nemitha yobushushu. Le ndlela ayifuni zixhobo zokuncedisa okanye imidiya yokupholisa, equka ukusebenza okulula kunye neendleko zemveliso eziphantsi kakhulu.
Nangona kunjalo, izinga layo lokuphola elicothayo kunye nokuhla kobushushu obungalinganiyo kukhokelela ngokulula kwiinkozo ezirhabaxa kunye nokwahlulwa kwesakhiwo ngaphakathi kwendawo yokusebenza, okubangela amandla aqhelekileyo, ubulukhuni kunye nokusebenza kokudinwa. Ke ngoko, ukupholisa umoya wendalo kufanelekile kuphela kwii-titanium zoshishino ezisemgangathweni ezifunekayo kunye nemigangatho yokunyamezelana okuchanekileyo okuphantsi. Ayisebenzi kwiindawo eziphambili ezichanekileyo nezinomthwalo ophezulu ezisetyenziswa kwimizi-mveliso yeenqwelo-moya kunye neyezonyango.
2Ukupholisa Umoya Onyanzelekileyo
Ukupholisa umoya ngokunyanzelwa yinkqubo ephuculiweyo nelawulekayo ephuculweyo ukusuka ekupholiseni kwendalo. Isebenzisa iifeni kunye nezixhobo zokuvuthela ezibhekisa kwicala ukuhambisa umoya ozinzileyo okhawulezayo kumphezulu wokubumba, ikhawulezisa ukusasazwa kobushushu kwaye inciphise umjikelo wonke wokuphola.
Xa kuthelekiswa nokupholisa kwendalo, ukupholisa umoya okunyanzelekileyo kufikelela ekuchithekeni kobushushu ngokukhawuleza nangokulinganayo. Kunokuphucula ulwakhiwo lwengqolowa engaphelelanga, kunciphise uxinzelelo lobushushu olushiyekileyo kwaye kuphucule kakhulu uzinzo loomatshini be-titanium forgings. Nangona kunjalo, le nkqubo ifuna ulawulo oluchanekileyo lweparameter. Isantya somoya esingafanelekanga, umgama ovuthuzayo okanye i-engile ziya kubangela ukupholisa okukhawulezileyo kwendawo, okubangela i-oxidation engaphezulu komphezulu kunye neengqimba eziqinileyo eziqinileyo, nto leyo ezisa ubunzima obongezelelekileyo bokucubungula umatshini kunye nokupolisha okulandelayo. Le ndlela yokupholisa isetyenziswa rhoqo kwiindawo zesakhiwo se-titanium eziphakathi ezineemfuno zokusebenza eziphakathi.
3Ukupholisa Ukucima Amanzi
Ukucima amanzi yinkqubo yokupholisa ekhawulezayo kakhulu kwii-titanium alloy forgings. Izinto zokusebenza ezishushu ezifakwe emanzini zifakwa ngokukhawuleza emanzini acocekileyo ukuze kufezekiswe ukwehla kobushushu ngokukhawuleza ngokutshintshiselana kobushushu okukhulu, kunye nokusebenza kakuhle kokupholisa kunokupholisa komoya. Esi siphumo sokucima ngokukhawuleza siphucula isakhiwo se-metallographic kwaye siphucula kakhulu amandla apheleleyo, ubulukhuni kunye nokumelana nokuguguleka kweendawo ze-titanium alloy.
Kwangaxeshanye, i-gradient yobushushu obugqithisileyo eveliswa ngexesha lokucinywa kwamanzi ibangela ngokulula uxinzelelo oluxineneyo olushiyekileyo, olukhokelela ekuguqukeni kwe-workpiece, ukuqhekeka okuncinci kwanokukrazulwa. Ulawulo oluqinileyo kwi-final gradient Ubushushu bokubumba, ixesha lokudlulisa kunye nokuma kokungena kwamanzi kuyafuneka ukuze kuthintelwe iziphene zomgangatho webhetshi. Okwangoku, ukucima amanzi kusetyenziswa kuphela kwii-titanium forgings ezikhethekileyo ezifuna amandla aphezulu kakhulu kunye nokuqina, kwaye akufanelekanga kwiindawo ezintsonkothileyo kunye nezixhobo ezichanekileyo ezinodonga oluncinci.
4Ukupholisa Ukucima ioyile
Ukucima ioyile kusebenzisa ioyile yokucima elawulwa bubushushu njengendlela yokupholisa, enesantya sokupholisa phakathi kokupholisa umoya kunye nokucima amanzi. Njengenkqubo yokupholisa elinganiselayo nezinzileyo ngesantya esiphakathi, inciphisa ngempumelelo iingozi zokuqhekeka kunye nokuguqulwa kwe-titanium forgings ngelixa iphucula ukugqitywa komphezulu kwaye inciphisa ukwakheka komaleko we-oxide.
Isitshixo sokucima ioyile efanelekileyo kukulawula ubushushu beoyile obuzinzileyo. Ukuguquguquka kobushushu okanye ukuguga kunye neendawo zokupholisa ezingcolisiweyo kuya kubangela ukupholisa okungalinganiyo kwendawo, okubangela umahluko kwisakhiwo kunye neziphene zokusebenza. Ke ngoko, imigca yemveliso yobungcali kufuneka ixhotyiswe ngeenkqubo zokulawula ubushushu ezichanekileyo kunye neendlela eziqhelekileyo zokuhluza kunye nokugcina. Ngozinzo oluphezulu kunye nokusebenza kweendleko ezipheleleyo, ukucima ioyile sesona sisombululo sokupholisa esiguquguqukayo kakhulu kwiiforgings ezininzi ze-titanium alloy ezichanekileyo.
5Ukupholisa iVacuum
Ukupholisa i-vacuum yinkqubo yokuchaneka okuphezulu kuphela kwe-high-purity titanium forgings. Izinto zokusebenza ziyaphola ngemitha yobushushu esebenzayo kwindawo evaliweyo ye-vacuum. Ihlukaniswe nomoya ngokupheleleyo, inkqubo ye-vacuum ngokusisiseko isusa i-oxidation yomphezulu, ukufunxwa komoya kunye nongcoliseko lomphezulu, igcina ubunyulu obuphezulu kunye neempawu zokuqala zoomatshini ze-titanium substrate.
Le ndlela inika isantya sokupholisa esikhawulezayo, ulwakhiwo lwangaphakathi olufanayo kwaye akukho ziphene zomphezulu, nto leyo eyenza ukuba ibe yinkqubo ekhethwayo yezixhobo zokuchaneka kweenqwelo moya kunye nokufakelwa kwe-titanium yodidi lwezonyango. Nangona kunjalo, ifuna utyalo-mali oluphezulu lwezixhobo, iinkqubo zokucubungula ezintsonkothileyo kunye nemijikelo yemveliso emide, nto leyo ekhokelela kwiindleko eziphezulu zokuvelisa. Ayifanelekanga ukuvelisa ngobuninzi iindawo ze-titanium eziqhelekileyo kwaye kufuneka ikhethwe ngokusekelwe kwindawo yemveliso kunye novavanyo lokwenyani lweendleko-inzuzo.
Isiphelo
Akukho nkqubo yokupholisa efanelekileyo ngokulinganayo kwimveliso yokubumba i-titanium alloy. Isisombululo esifanelekileyo sixhomekeke kwiimfuno zokwenyani zemveliso. Ukupholisa umoya wendalo okungabizi kakhulu kulungele iindawo eziqhelekileyo zesakhiwo; ukupholisa umoya okunyanzelekileyo kunye nokucima ioyile kuhambelana nezinto zokusebenza ezineemfuno zokuchaneka okuphakathi kunye nozinzo; ukucima amanzi okulawulwa ngokungqongqo kusetyenziswa kwiindawo ezikhethekileyo ezinamandla aphezulu; ukupholisa i-vacuum kuyimfuneko kwi-aerospace ecocekileyo kakhulu, echanekileyo kakhulu kunye ne-forgings yomgangatho wezonyango.
Ukuhambelana ngokuchanekileyo kweendlela zokupholisa ngokusekelwe kudidi lwe-titanium alloy, ulwakhiwo lwe-workpiece kunye neemeko zenkonzo, kunye nolawulo oluqinileyo lweeparameter kuyo yonke inkqubo, kunokuzinzisa ulwakhiwo lwe-metallographic kunye neempawu zoomatshini zeendawo ezibunjiweyo. Le yeyona nto ibalulekileyo ekuqinisekiseni uzinzo lwenkonzo yexesha elide kunye nokwandisa ubomi benkonzo yezixhobo ze-titanium alloy ezigqityiweyo.
